  • Does lookaround affect which languages can be matched by regular expressions?

    - by sepp2k
    There are some features in modern regex engines which allow you to match languages that couldn't be matched without that feature. For example the following regex using back references matches the language of all strings that consist of a word that repeats itself: (.+)\1. This language is not regular and can't be matched by a regex, which does not use back references. My question: Does lookaround also affect which languages can be matched by a regular expression? I.e. are there any languages that can be matched using lookaround, which couldn't be matched otherwise? If so, is this true for all flavors of lookaround (negative or positive lookahead or lookbehind) or just for some of them?

  • iPhone - Change app icon pointed to by info.plist within the application?

    - by Batgar
    Is there any way to change the 47x47 PNG, pointed to within info.plist, for the iPhone springboard icon from within code? I understand I can add a translation and change the springboard icon per language that the iPhone supports via a changed info.plist per language, but I would like to change the springboard icon for my iPhone app based on a user preference within the app. Any ideas? I haven't tried this, but can a file be copied over another within an app bundle? Could I ship with info.plist pointing to "base.png" then replace "base.png" with another PNG I package with my app from within code? Thanks. --Batgar

  • SCons does not clean all files

    - by meowsqueak
    I have a file system containing directories of "builds", each of which contains a file called "build-info.xml". However some of the builds happened before the build script generated "build-info.xml" so in that case I have a somewhat non-trivial SCons SConstruct that is used to generate a skeleton build-info.xml so that it can be used as a dependency for further rules. I.e.: for each directory: if build-info.xml already exists, do nothing. More importantly, do not remove it on a 'scons --clean'. if build-info.xml does not exist, generate a skeleton one instead - build-info.xml has no dependencies on any other files - the skeleton is essentially minimal defaults. during a --clean, remove build-info.xml if it was generated, otherwise leave it be. My SConstruct looks something like this: def generate_actions_BuildInfoXML(source, target, env, for_signature): cmd = "python '%s/bin/create-build-info-xml.py' --version $VERSION --path . --output ${TARGET.file}" % (Dir('#').abspath,) return cmd bld = Builder(generator = generate_actions_BuildInfoXML, chdir = 1) env.Append(BUILDERS = { "BuildInfoXML" : bld }) ... # VERSION = some arbitrary string, not important here # path = filesystem path, set elsewhere build_info_xml = "%s/build-info.xml" % (path,) if not os.path.exists(build_info_xml): env.BuildInfoXML(build_info_xml, None, VERSION = build) My problem is that 'scons --clean' does not remove the generated build-info.xml files. I played around with env.Clean(t, build_info_xml) within the 'if' but I was unable to get this to work - mainly because I could not work out what to assign to 't' - I want a generated build-info.xml to be cleaned unconditionally, rather than based on the cleaning of another target, and I wasn't able to get this to work. If I tried a simple env.Clean(None, "build_info_xml") after but outside the 'if' I found that SCons would clean every single build-info.xml file including those that weren't generated. Not good either. What I'd like to know is how SCons goes about determining which files should be cleaned and which should not. Is there something funny about the way I've used a generator function that prevents SCons from recording this target as a Clean candidate?

  • Hadoop streaming with Python and python subprocess

    - by Ganesh
    I have established a basic hadoop master slave cluster setup and able to run mapreduce programs (including python) on the cluster. Now I am trying to run a python code which accesses a C binary and so I am using the subprocess module. I am able to use the hadoop streaming for a normal python code but when I include the subprocess module to access a binary, the job is getting failed. As you can see in the below logs, the hello executable is recognised to be used for the packaging, but still not able to run the code. . . packageJobJar: [/tmp/hello/hello, /app/hadoop/tmp/hadoop-unjar5030080067721998885/] [] /tmp/streamjob7446402517274720868.jar tmpDir=null JarBuilder.addNamedStream hello . . 12/03/07 22:31:32 INFO mapred.FileInputFormat: Total input paths to process : 1 12/03/07 22:31:32 INFO streaming.StreamJob: getLocalDirs(): [/app/hadoop/tmp/mapred/local] 12/03/07 22:31:32 INFO streaming.StreamJob: Running job: job_201203062329_0057 12/03/07 22:31:32 INFO streaming.StreamJob: To kill this job, run: 12/03/07 22:31:32 INFO streaming.StreamJob: /usr/local/hadoop/bin/../bin/hadoop job -Dmapred.job.tracker=master:54311 -kill job_201203062329_0057 12/03/07 22:31:32 INFO streaming.StreamJob: Tracking URL: http://master:50030/jobdetails.jsp?jobid=job_201203062329_0057 12/03/07 22:31:33 INFO streaming.StreamJob: map 0% reduce 0% 12/03/07 22:32:05 INFO streaming.StreamJob: map 100% reduce 100% 12/03/07 22:32:05 INFO streaming.StreamJob: To kill this job, run: 12/03/07 22:32:05 INFO streaming.StreamJob: /usr/local/hadoop/bin/../bin/hadoop job -Dmapred.job.tracker=master:54311 -kill job_201203062329_0057 12/03/07 22:32:05 INFO streaming.StreamJob: Tracking URL: http://master:50030/jobdetails.jsp?jobid=job_201203062329_0057 12/03/07 22:32:05 ERROR streaming.StreamJob: Job not Successful! 12/03/07 22:32:05 INFO streaming.StreamJob: killJob...

  • XML serialization of a collection in C#

    - by Archana R
    I have two classes as follows: public class Info { [XmlAttribute] public string language; public int version; public Book book; public Info() { } public Info(string l, int v, string author, int quantity, int price) { this.language = l; this.version = v; book = new Book(author, quantity, price); } } public class Book { [XmlAttribute] public string author; public int quantity; public int price; [XmlIgnore]public int total; public NameValueCollection nvcollection = new NameValueCollection(); public Book() { } public Book(string author, int quantity, int price) { this.author = author; this.quantity = quantity; this.price = price; total = quantity * price; nvcollection.Add(author, price.ToString()); } } I have created an ArrayList which adds the two instances of Info class as follows: FileStream fs = new FileStream("SerializedInfo.XML", FileMode.Create); List<Info> arrList = new List<Info>(); XmlSerializer xs = new XmlSerializer(typeof(List<Info>)); Info pObj = new Info("ABC", 3, "DEF", 2, 6); Info pObj1 = new Info("GHI", 4, "JKL", 2, 8); arrList.Add(pObj); arrList.Add(pObj1); xs.Serialize(fs, arrList); fs.Close(); But when I try to serialize, I get an exception as "There was an error reflecting type 'System.Collections.Generic.List`1[ConsoleApplicationSerialization.Info]'." Can anyone help me with it? Also, instead of namevaluecollection, which type of structure can i use?

  • Celery / Django Single Tasks being run multiple times

  • What's a good approach to adding debug code to your application when you want more info about what's going wrong?

    - by Andrei
    When our application doesn't work the way we expect it to (e.g. throws exceptions etc.), I usually insert a lot of debug code at certain points in the application in order to get a better overview of what exactly is going on, what the values for certain objects are, to better trace where this error is triggered from. Then I send a new installer to the user(s) that are having the problem and if the problem is triggered again I look at the logs and see what they say. But I don't want all this debug code to be in the production code, since this would create some really big debug files with information that is not always relevant. The other problem is that our code base changes, and the next time, the same debug code might have to go in different parts of the application. Questions Is there a way to merge this debug code within the production code only when needed and have it appear at the correct points within the application? Can it be done with a version control system like git so that all would be needed is a git merge? P.S. The application I'm talking about now is .NET, written in C#.

  • Which programming language should i choose? (much more info inside) [closed]

    - by Andreas
    I am not completely sure if this is the right place to put this question, but since it's the programming thread I guessed that there's many experienced programmers here. :) Ok, hello! My name is Andreas and I am a 16 years old guy from Norway. For some time now I've wanted to learn a programming language. Six months ago I started learning C++, but quit withing a week due to lack of motivation. The same thing happend only 2 months ago when I tried to learn Lua. I wanted to program mods to the game Garry's mod, and was really motivated. Then I stopped playing the game, and the programming stopped with it. Today though I am ready again. The only difference is that I am not completely sure what I want to do with the language. I only want to create something, and I miss the progress of failing and enduring hard work until I finally solve the problem I've worked on for hours. What I am trying to say is; Is there any program out there that allows me, a complete noob (I didn't learn that much in a week, so I like to call myself a beginner), to create apps, mods or something similar but at the same time being qualified as a first time language? I was thinking of Java, because Android, Minecraft and many other applications and games use it. But I've heard that it is going to be replaced by a program called HTML 5 (whatever that is), is this true? I certainly don't want to spend many hours of my life on something that is useless in a year or two. Hopefully I didn't make this too complicated. I know that it is hard to recommend something when I don't have a goal, but I really don't know what to say. Have a good day kind folks! - Andreas EDIT:* I did not know that this was an off topic question, really sorry!

  • Bad idea to display mail server info in public github project?

    - by kentcdodds
    I have the project for work that requires me to send e-mails to people using our work mail server. The server doesn't require authentication. Part of my project is using a Java-Helper I'm developing on GitHub. I don't know if I completely understand how it all works, but I'm guessing it would be a bad idea to have the server information available on GitHub for the world to see. Is this correct? After thought: I'm not going to put it in the Java-Helper because that wouldn't be helpful for anyone but me. but I'm still curious to know the answer to this question :) Thanks!

  • Some info about SD card patitions after the use of the dd statment and some oiters doubts?

    - by AndreaNobili
    I am not very experienced using Linux and I have the following situation that cause me some doubts. I have wrote RaspBian (the RaspBerry linux distribution) on an SD card using Ubuntu dd statment: sudo dd if=2014-01-07-wheezy-raspbian.img of=/dev/sdb bs=1024 So if now I perform the fdisk -l statment I obtain that I have 2 partitions related to my SD card, that are the followins: Dispositivo Boot Start End Blocks Id System /dev/sdb1 8192 122879 57344 c W95 FAT32 (LBA) /dev/sdb2 122880 5785599 2831360 83 Linux And now the first doubt: the dd statment create on the SD card two partitions: 1) /dev/sdb1 that is a litle FAT32 partition (what it means (LBA)?) 2) /dev/sdb2 that is a larger Linux ext3 partition Ok...the doubt is: why it also create to me a FAT32 partition and not only a Linux ext3 partition? Ok...if I go into my computer resource I can see a device (related to my SD card) into the devices list that contains some RaspBian file, following a screenshot: And if I see the property of this device I obtain this: So, looking at the previous screenshot it seems to me that this is the small FAT32 partition, and now I have the followings doubts: If it is the smallest FAT32 partition, what contains? The RaspBian boot or what? Why, in the devices list, I have only the FAT32 partition and not also the Linux one (/dev/sdb2), to see it have I to mount it? how? Tnx

  • WebCenter Content Web Search Performance: Do you really need that folder path info?

    - by Nicolas Montoya
    End-users want content at their fingertips at the speed of thought if possible. When running search operations in the WebCenter Conter Web Interface every second or fraction of a second improvement does matter. When doing some trace analysis on the systemdatabase tracing on a customer environment, we came across some SQL queries that were unnecessarily being triggered! These were related to determining the folder path for every entry part of the search result set. However, this folder path was not even being used as part of the displayed information in the user interface.Why was the folder path information being collected when it was not even displayed in the UI? We found that the configuration parameter 'FolderPathInSearchResults' was set to 'true' under Administration > Admin Server > General Configuration > Additional Configuration Variables as shown below:When executing a quicksearch by keyword we were getting 100 out of 2280 entries in the first page of the result set.When thera 'FolderPathInSearchResults' configuration parameter is set to 'true', the following queries appear in the systemdatabase tracing:100 executions for a query on the FolderFiles table for each of the documents displayed in the first page:>systemdatabase/6       12.13 11:17:48.188      IdcServer-199   1.45 ms. SELECT * FROM FolderFiles WHERE dDocName='SLC02VGVUSORAC140641' AND fLinkRank=0[Executed. Returned row(s): true]382 executions for a query of the folders tables - most of the documents that match the keyword criteria are at a folder depth level of three or four:>systemdatabase/6       12.13 11:17:48.114      IdcServer-199   2.57 ms. SELECT FolderFolders.*,FolderMetaDefaults.* FROM FolderFolders,FolderMetaDefaults WHERE FolderFolders.fFolderGUID=FolderMetaDefaults.fFolderGUID(+) AND((FolderFolders.fFolderGUID = '1EB8E527E19B09ED3FE82EE310AEA13A' ) )[Executed.Returned row(s): true]By setting this 'FolderPathInSearchResults' configuration parameter to 'false', the above queries were no longer reported in the Server Output System Audit Information.Now, let's consider a practical scenario:Search result set page = 100Average folder depth der document in the search result set: 5The number of folder path related queries will be: 100 + 5*500 = 600If each query takes slightly over 3 ms. You would have 2000 ms (2 seconds) spent in server time to get this information.The overall performance impact goes beyond seerver time execution, as this information needs to travel from the server to the browser. If the documents are further nested into the folder hierarchy, additional hundreds of queries may be executed. If folder path is not being displayed in the end-user interface profile, your system may be better of with the 'FolderPathInSearchResults' configuration parameter disabled.

  • Why can't get past the user info screen when installing 10.10?

    - by Faceless
    I have a Dell Inspiron 1318 (07-08?) with an Intel Cored 2 Duo Processor and 3 GB of RAM. I can run Ubuntu 10.10 from the disk, but I've tried to install it three times with no success. As the files are installing, the program asks me to enter my user information. I'm fine through the time zone screen, and fine through the keyboard screen. But when it asks me to set my used name and password, the "next" button stays ghosted out no matter what I enter. Eventually, the installation gets to the point where it says it's waiting for me, but no matter what I do I can't get the "next" button to click. I'm a complete newbie, and I've been stuck at the same spot three times. If anyone has any idea what's going wrong, I'd love to hear about it.

  • Parsing glGetShaderInfoLog() to get error info. Is this reliable, or is there a better way?

    - by m4ttbush
    I want to get a list of errors and their line numbers so I can display the error information different to how it's formatted in the error string, and also show the line in error. It looks easy enough to just parse the result of glGetShaderInfoLog(), look for "ERROR:" then read the next number up to : and then the next, and then the error description up to the next newline. But the OpenGL docs say "Application developers should not expect different OpenGL implementations to produce identical information logs." Which makes me worry that my code may behave incorrectly on different systems. I don't need them to be identical, I just need them to follow the same format. So is there a better way to get a list of errors with line number separate, is it safe to assume that they'll always follow the "ERROR: 0:123:" format, or is there simply no reliable way to do this? Thanks!

  • Send some form info to a PHP page to be processed without going to that page? [closed]

    - by zuko
    Okay, so I'm not very familiar with php. I have a very simple form, just 2 text fields. All I want to do is, after validating with JavaScript, send these two string fields in an email to a pre-defined email address. I understand how JavaScript works on the client side; you can respond to user events, etc. And PHP is server-side. What I'm having trouble grasping and figuring out is how do I run PHP functions, etc when I want? I figured out how to use the 'action' attribute of the form to send the data via POST to another PHP page. But this simply opens that page. I don't want to open the page I just want to do some processing and send a message back to the page the user is still on. How do I go about something like that? Thanks.

Here's my code: $date_regex = '(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d'; $test_date = '03/22/2010'; if(preg_match($date_regex, $test_date)) { echo 'this date is formatted correctly'; } else { echo 'this date is not formatted correctly'; } When I run this, it still echoes 'this date is not formatted correctly', when it should be saying the opposite. How do I set this regular expression up in php?

  • Is it possible to "learn" a regular expression by user-provided examples?

    - by DR
    Is it possible to "learn" a regular expression by user-provided examples? To clarify: I do not want to learn regular expressions. I want to create a program which "learns" a regular expression from examples which are interactively provided by a user, perhaps by selecting parts from a text or selecting begin or end markers. Is it possible? Are there algorithms, keywords, etc. which I can Google for? EDIT: Thank you for the answers, but I'm not interested in tools which provide this feature. I'm looking for theoretical information, like papers, tutorials, source code, names of algorithms, so I can create something for myself.

  • Why would I see PHP NOTICE and ERRORs when running a script as a regular user, but not as root?

    - by Shawn
    As far as I can tell, there's no difference between the error reporting or message redirection between users. They both use the same PHP ini. However, when I run a script as a regular user, I get tons of NOTICES, when run as root, I get none. When starting PHP interactive mode as a regular user, I get two PHP Warnings that 'memcache' and 'xmlwriter' are already loaded; when starting as the root user, I get no warnings. I know that I should be fixing the warnings, not "making the warnings go away;" that's on the ticket. The question is, Why are the users treated differently? Why does a regular user get notices and warnings, but root does not, even if their error reporting are the same?

  • VMware "boot screen" - add info like contact, phone number, etc.?

    - by TheCleaner
    I've tried searching Google and VMware's KB but maybe I'm not typing the right search criteria...only finding ways to fix problems with booting or screen issues. On the default boot screen of a host it looks similar to this picture from GIS: I'm curious if it is possible somehow to make it look like this instead (adding custom details): I know for the most part the info is "useless" since it is administered remotely, etc. But when I deploy standalone hosts to branch offices, it'd be nice for them to see this type of info on the boot screen. I may also include the VMs hosted on it (again on standalone hosts). Normal monitoring, etc. will be done remotely. This is strictly for odd times when the branch contact may say "the electricians are saying they need to turn off this circuit but I have no idea who to call in IT to tell them this box needs to be shut down" or similar. Anyone who has dealt with small branch offices can tell you that if it isn't labeled they easily forget what it is for and will simply say after the incident "I didn't know what it was or who to call." Possible?

  • Which credentials should I put in for Google App Engine BulkLoader at development server?

    - by Hoang Pham
    Hello everyone, I would like to ask which kind of credentials do I need to put on for importing data using the Google App Engine BulkLoader class appcfg.py upload_data --config_file=models.py --filename=listcountries.csv --kind=CMSCountry --url=http://localhost:8178/remote_api vit/ And then it asks me for credentials: Please enter login credentials for localhost Here is an extraction of the content of the models.py, I use this listcountries.csv file class CMSCountry(db.Model): sortorder = db.StringProperty() name = db.StringProperty(required=True) formalname = db.StringProperty() type = db.StringProperty() subtype = db.StringProperty() sovereignt = db.StringProperty() capital = db.StringProperty() currencycode = db.StringProperty() currencyname = db.StringProperty() telephonecode = db.StringProperty() lettercode = db.StringProperty() lettercode2 = db.StringProperty() number = db.StringProperty() countrycode = db.StringProperty() class CMSCountryLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'CMSCountry', [('sortorder', str), ('name', str), ('formalname', str), ('type', str), ('subtype', str), ('sovereignt', str), ('capital', str), ('currencycode', str), ('currencyname', str), ('telephonecode', str), ('lettercode', str), ('lettercode2', str), ('number', str), ('countrycode', str) ]) loaders = [CMSCountryLoader] Every tries to enter the email and password result in "Authentication Failed", so I could not import the data to the development server. I don't think that I have any problem with my files neither my models because I have successfully uploaded the data to the appspot.com application. So what should I put in for localhost credentials? I also tried to use Eclipse with Pydev but I still got the same message :( Here is the output: Uploading data records.

  • Cognos 8.3: Can I use parameters in conditional style expressions?

    - by Jacob
    Hi, I have Start Date and End date parameters that work fine as filters on a query, as follows: [EMR Reporting].[Appointments].[Appointment Date] between ?Start Date? and ?End Date? But when I attempt to apply conditional styles to a field based on ?Start Date?, the report blows up. Should I be able to use parameter values in conditional style expressions, or is this not supported for some reason? Thanks!
